When your laptop turns off almost immediately after turning it on, it can mean a lot of things that could be wrong. In this article, we will look at the causes and remedies. Usually the problem of why your Lenovo laptop starts and shuts down suddenly is hardware or software related, like most computer problems. A damaged internal component or certain software may cause it to suddenly shut down. Replacing Lenovo parts from the “Lenovo Parts” online store will help you fix this problem. However, you need to know which part of the laptop needs replacement.
Why does my laptop start up and then shut down?

  1. Low battery
  2. Faulty power supply
  3. Immediate overheating at startup
  4. Electric shorts
  5. Defective power button
  6. Damaged internal components
  7. Loose component / wire connection
  8. Computer virus

These problems are most often the cause of accidental laptop shutdowns. Some are more serious than others and may require purchasing a new laptop. However, we will tell you how to diagnose these common problems and, if possible, how to fix them!

Low Battery

If your laptop won’t boot, then the first thing you should check is the battery. Since it can no longer hold a charge. This could be for one of many reasons: either the battery is old or the power adapter is damaged and won’t charge the laptop.

If the battery is removable, remove it from the laptop and plug it into a charger. If after that the laptop turns on, then the problem is with the battery. If your laptop battery is more than a few years old, it might be a good time to replace it. If your laptop has a removable battery, or the internal battery is very easy to get out. You can simply order it online and replace it yourself.

However, if your battery is not one of these cells, as in a traditional modern MacBook. Then send it to the manufacturer for battery replacement. If the laptop is still under warranty, you can claim it for a battery problem in order to get a replacement.

Defective Power Adapter

If you are sure the battery is not the problem, then the next thing to move on is the power adapter. Power adapters fail quite often, especially if you live in a country where the voltage is known to fluctuate from the mains. If you have a spare power adapter or have one lying around with friends, check your laptop with it. If it turns on without accidentally turning it off, then it is best to replace the adapter. Also, when buying power adapters and batteries for your laptop, never compromise on the price. Third-party batteries and power adapters may actually supply high or low current to your laptop, which could actually damage it. Believe me, I proceed from my experience in this matter. So make sure

Faulty Power Connector

This is one that most people often forget about, but it is not uncommon for the power connector port to be faulty. You will most likely expose the power connector to stress when you leave it charging. Its internal parts may have been damaged and it can no longer charge the laptop. This may or may not be a relatively straightforward fix given how corrupted the port is. This is probably the best option to send your laptop to the manufacturer for repair, or take it to a laptop workshop. They can fix the port or replace it entirely.

Immediate Overheat On Startup

Overheating can be a very likely problem for accidental shutdowns. Due to clogging of the cooling system with dust or old thermal paste on the processor. Your laptop may no longer stay cold enough to prevent overheating and will therefore shut down to prevent damage. This fix can be done at home if you have experience with laptop internals. Just google your laptop’s name and “how to open” and you will find a guide that will give you step-by-step instructions on how to open it. Once inside, inspect the cooling fans and radiators. If they are covered in grime and dust, chances are you just found the cause of your overheating problems. Take a can of compressed air and blow all the dirt and dust off the laptop. Double check that your fans are still working. If your fans stop spinning for any reason, no airflow will flow through the system. So replace them if necessary. If that doesn’t fix the problem, the next thing to check is your processor’s thermal grease. Thermal grease is what transfers heat from the CPU die to your laptop’s copper cooling system. If your laptop is several years old, you should replace the thermal paste immediately.

Faulty Power Button

A faulty power button has been known to cause the laptop to shut down accidentally. If your power button is starting to stick or the button mechanism is just not as tactile as the first day you received it. Most likely, the button is shorted or even stuck to the body. This can cause your laptop to turn off immediately after turning it on, because it looks like the power button is constantly being pressed. You can try unplugging the power button or figuring out what’s causing it to stick. Try blowing compressed air into and around the power button. There may be some debris stuck inside the button, causing it to either stick or short-circuit. If that doesn’t work, you might need to replace the power button.

Now let’s move on to the most expensive possible reason for which you are experiencing an outage, namely damage to internal components. Sometimes a burned-out motherboard, a broken processor, or even just a loose / damaged wire can cause your laptop to shut down. Start by opening your laptop and examining the physical condition of its internals. Pay attention to burn marks or smoke smells. Try removing the flash drives from the RAM one by one to check if the laptop boots.

Sometimes your problem may be a dead RAM stick, be sure to check if any debris has gotten into the slots of the RAM slots. Then you can try to remove the hard drive or solid state drive to see if the laptop stays on at this time, even if it doesn’t boot into the OS. If something cannot be repaired, then, unfortunately, there is no independent solution. You are either stuck buying a new laptop or looking for spare parts for it.

Also check all wires inside the laptop to make sure they are not damaged. Remove and reconnect all wires in the system to see if that solves the problem. A loose connection can be the reason for your disconnections. If you find a damaged wire, replace it immediately to avoid damaging the laptop.

After you investigate all possible physical causes of the problem. The next most likely candidate is a computer virus. To better deal with this, you need to install an antivirus as soon as possible. If you have important data backed up somewhere, it might be a good idea to perform a fresh installation of Windows. There is no full guarantee that you have removed the virus, even if you have performed multiple scans on your laptop. After all we’ve discussed, you should be able to diagnose and fix most random laptop shutdown problems.
